IMPROVEMENT IN BRUSHES.

Specification forming part of Letters Patent No. 120,523, dated October31, 1871.

To all whom it may concern:

Be it known that I, DANIEL W. LAPHAM, of Baltimore, in the county ofBaltimore and inthe State of Maryland, have invented certain new anduseful Improvements in the Manufacture of Brushes; and do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accom ran yin g drawing making a part of thisspecification, in which- Figure 1 is a perspective view of a brushconstructed in accordance with my improved method, and Fig. 2 is acentral longitudinal section of the same.

Letters oflike name and kind refer to like parts in each of the figures.

The object of my invention is to increase the durability and finish andlessen the expense of brushes in which the bristles are bound upon oraround the handle; and it consists in constructing the brush end of thehandle with a series of conical faces, to or upon which the bristles aresecured, substantially as and for the purpose hereinafter specified.

In brushes as ordinarily constructed an open space is left within thebristles at the end of the handle, which space is but partly concealedwhen the brush is new, and as the same becomes worn is a source of muchannoyance. In addition to the foregoing objection, much difficulty isexperienced in properly securing the bristles together and to thehandle, so as to enable them to be worn out before becoming disengaged.To obviate these difficulties I construct my handle A with one or moregrooves at its brush end, each of which grooves forms a section of acone, B, the base of which is downward, and its apex joined to the baseof the next cone above; or, if the highest, to the lower portion of thehandle. The cones B are preferably decreased regularly in size from theuppermost to the lowest. As thus formed, the bristles 0, having twicethe length desired, are bound at their centers in layers upon and aroundthe faces of the cones, commencing with the lowest. The upper portionsof said bristles are then doubled downward upon or against their lowerportions, and a wire wound one or more times around their upper doubledends, immediately below the first wire or cord, by which means saidbristles are firmly secured to or upon the handle, and cannot be removedtherefrom by any ordinary usage. After the outer and upper layer issecured in place a woven elastic band, D, is placed over or around itsupper end, immediately below an outward-projecting flange or bead, a,where it is held by its elasticity, and furnishes a neat and durablecovering for said part. The especial advantage of the conical face is,that it prevents the layer of bristles from being withdrawn from thehandle without the binding wire or cord is first broken or removed,while the arrangement of the series of faces causes the confined ends ofthe bristles to occupy less than ordinary space. In addition to theforegoing, for the inner layers of bristles, less length of stock isrequired, and consequently a saving in cost is eifected.

Having thus fully set forth the nature and merits of my invention, whatI claim as new, 1s

As a new article of manufacture, a brush composed of a handle, A,provided with a series of conical faces, B, for the reception of and incombination with the bristles G, substantially as and for the purposespecified.

In testimony that I claim the foregoing I have hereunto set my hand this3d day of June, 1871.

DANIEL W. LAPHAM.
